In favor of God and man

Luke 2:40-52
The child Jesus grew and became strong, filled with wisdom. And the favor of God was upon him.
The boy Jesus went to Jerusalem  with his parent, but he stayed in Temple sitting among the teachers, listening to them and asking them questions. All who heard him were amazed at his understanding and his answers.
Jesus answered his mother, "Why were you looking for me? Did you not know that I must be in my Father's house（I must be about my Father's business?）?" Boy Jesus went down with them and came to Nazareth and was submissive to them.
Jesus increased in wisdom and in stature and in favor with God and man.
Why?
The time of Jesus have not come, so he submissive to his parent in the world.
Jesus grew up with wisdom for favor of God was upon him.
Boy Jesus already have known the words of God, for he is the God.
Boy Jesus mentioned one thing that is his mission in this world - I must be about my father's business.
I must honor the name of God by good witness in my any business in the world that God gives me.
How?
What is my business in this world? Make each matter in favor of God and man.
